← TechnologyWhich risk increases when dithering magnitude decreases in hydraulic flow control?
A)System resonance and instability
B)Actuator over-heating significantly rises
C)Control valve stiction worsens✓
D)Pump cavitation risk reduces drastically
💡 Explanation
Lower dithering magnitude implies weaker oscillation around a valve's null point; the stick-slip effect rises because the control valve static friction is not properly overcome, therefore stiction worsens rather than improving pressure control.
